7(8 The Wohurn Thxperiments on ^‘■Potato DiseaseJ 
Thus it will be seen that, while the A plots were, generally 
speaking, rather less attacked than the B and C plots, there was only 
one instance — the “ White Elephant — where there Vf as a marked 
difference in favour of the A’s. This, however, it should be noted, 
was where disease was most prevalent. After September 3 the 
disease became much worse on all the plots. As the crop approached 
ripeness, a considerable difference was noted between the tops which 
had been sprayed (A’s and B’s) and those which had not been dressed. 
The tops of the sprayed plots remained green long after the haulms 
on the C plots had died down. All the remaining crops were dug 
and weighed October 11 to 25, 
Notes on the Varieties . — The following notes were taken by Mr. 
Elliott upon the relative qualities of the different varieties : — 
“ Beauty of Hebron ” 
“ Myatt’s Asbleaf ” 
“ Early Puritan ” . 
" Early Rose ” 
" Dalmahoy ” 
“ Regent ” . 
“ White Elephant ” 
“ Reading Giant ” 
Champion ” . 
“Imperator” 
“ Schoolmaster ” . 
“ Victoria ” . 
Good early cropper ; clean skin ; shallow eye ; 
very saleable. 
An early kidney potato ; small cropper and hardly 
a field variety ; the skin becomes scabby on 
the Woburn land. 
Early and fair cropper, but runs rather small. 
Early, but not very saleable, as it is very apt to 
grow pink right through the tuber. 
Medium early ; good cropper ; not a coarse sldD, 
but rather scabby. 
Coarse-skinned ; deep-eyed ; very unsaleable. 
Good cropper (although liable to disease) ; cccks 
well ; saleable, but does not keep well. 
Good-looking potato ; very heavy cropper — clean 
thin skin ; saleable. 
Coarse “ cattle ” potato ; deep-eyed ; goes hollow 
in centre and becomes rotten there ; almost 
unsaleable. 
Very good cropper ; clean skin ; plant has very 
large tops ; quite saleable. 
Very fiiir cropper, but scabby, and not a saleable 
potato. 
Average cropper ; good cooker ; apt to grow out 
of ground instead of pushing downwards. 
From these notes, and the crop Aveights that follow, it will be 
o-athered that the best potato among the “ earlies ” Avas the “ Beauty 
of Hebron,” among the “ medium ” crops the “ Reading Giant,” and 
of the “ late ” varieties the “ Imperator.” 
The potatoes when dug Av^ere cliA'ided into sound and diseased 
tubers, Avhich Avere weighed separately. The AA'eights per acre of 
the respective varieties are given in the accompanying tables (pp. 
780-81), which also shoAv the influence of the early and late 
applications'^of the bouillie dressing. 
Before proceeding to discuss the tables, the experiments in steep- 
in" the tubers before planting may be dismissed briefly by saying 
that they were quite unsuccessful. With regard to steeping in 
sulphate of copper, it was pretty well knoAvn to the scientific officers
